<p>seems bad.  doesn't include any useful diagnostic prior to ICE'ing. Its probably because the HAIR builder assumes you cannot have floating point numbers as array lengths. (and maybe that is supposed to be impossible in the HAIR.)</p>

<p>(if I'm correct about this being in the WG-async-await queue, we probably need to figure out some  system for marking things as "in the triage queue for team X".  Or more specifically, some way for <em>T-compiler</em> to tag something as "not actually nominated for us...")</p>
